Whodunnit?

We had only one guiser last night: he is over thirty and sang a wee song to earn his dinner and three packs of Percy Pigs.

We also had a full sweet dish at the start of the evening in case small ghosts and goblins called. Shouldn't it still be full if we had no guisers? But alas, it's half empty!! This seems to be a mysterious whodunnit.

Mind you, not as much of a whodunnit as Book 7 in Susan Hill's wonderful Simon Serrailler series, A Question of Identity, which I have almost finished. Guess what I'm going to do this afternoon?
